Viewbinding配置

android { viewBinding { enabled = true } 
} 

Activity封装

import android.os.Bundle
import android.view.LayoutInflater
import androidx.appcompat.app.AppCompatActivity
import androidx.viewbinding.ViewBinding/*** @explain* @author Created by PGC on 2023/12/11 9:56.*/
abstract class BaseBindingActivity<VB : ViewBinding>(private val inflate: (LayoutInflater) -> VB) : AppCompatActivity() {lateinit var binding: VBoverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)binding = inflate(layoutInflater)setContentView(binding.root)}}

Activity使用

class ExampleActivity : BaseBindingActivity<ActivityExampleBinding>(ActivityExampleBinding::inflate) {@SuppressLint("SetTextI18n")override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)binding.exampleBindingBt.text = "binding"}
}

Fragment封装

abstract class BaseBindingFragment<VB : ViewBinding>(private val inflater: (LayoutInflater, ViewGroup?, Boolean) -> VB) :Fragment() {private var _binding: VB? = nullval binding: VB get() = _binding!!override fun onCreateView(inflater: LayoutInflater,container: ViewGroup?,savedInstanceState: Bundle?): View? {_binding = inflater(inflater, container, false)return binding.root}override fun onDestroyView() {super.onDestroyView()_binding = null}}

Fragment使用

class ExampleFragment : BaseBindingFragment<FragmentExampleBinding>(FragmentExampleBinding::inflate) {@SuppressLint("SetTextI18n")override fun onViewCreated(view: View, savedInstanceState: Bundle?) {super.onViewCreated(view, savedInstanceState)binding.exampleBindingTv.text="binding"}
}

Dialog封装

abstract class BaseBindingDialog<VB : ViewBinding>(context: Context,themeResId: Int,private val inflate: (LayoutInflater) -> VB) : Dialog(context, themeResId) {lateinit var binding: VBconstructor(context: Context, inflate: (LayoutInflater) -> VB) : this(context, 0, inflate)override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)binding = inflate(layoutInflater)setContentView(binding.root)}
}

Dialog使用

class ExampleDialog(context: Context): BaseBindingDialog<DialogExampleBinding>(context,0,DialogExampleBinding::inflate) {override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)binding.tv.text = "binding"}
}
